CSV export with non-UTF8 characters

Dear everyone,
Some customers reported the issue with CSV Export feature at Back-end of OS Property. In case their properties contain non-UTF8 characters, the CSV exported file will contain strange characters. We have checked that function again and found that is the issue of OS Property. This issue will be fixed in OS Property 2.7.5, but if you are using previous OS Property version. You can fix the error by following bellow steps
1. Open file: root > administrator > components > com_osproperty > classes > csvexport.php
2. find this line
fputcsv($fp, $labels,$configClass);
and put this line
fwrite($fp,"\xEF\xBB\xBF");
above it.

Good luck
Dam
